无法禁用 systemd 用户计时器，未知方法DisableUnitFilesWithFlagsAndInstallInfo

我有一个简单的 systemd 服务和计时器，~/.config/systemd/user用于构建我最喜欢的程序的夜间图像：

# ~/.config/systemd/user/kicad-build.service
[Unit]
Description=KiCAD nightly builder

[Service]
Type=simple
StandardOutput=null
ExecStart=/bin/bash /home/jan/kicad-nightly-builder/build.sh

# ~/.config/systemd/user/kicad-build.timer
[Unit]
Description=KiCAD nightly build timer

[Timer]
OnCalendar=daily
Persistent=true
RandomizedDelaySec=7200

[Install]
WantedBy=timers.target

现在我想禁用计时器，因为我不再需要夜间构建：

[jan@memory-alpha user]$ systemctl --user stop kicad-build.timer

[jan@memory-alpha user]$ systemctl --user disable kicad-build.timer
Failed to disable unit: Unknown method DisableUnitFilesWithFlagsAndInstallInfo or interface org.freedesktop.systemd1.Manager.

这里发生了什么？为什么systemctl找不到合适的方法来禁用该单元？计时器仍然启用：

[jan@memory-alpha user]$ systemctl --user status kicad-build.timer
○ kicad-build.timer - KiCAD nightly build timer
     Loaded: loaded (/home/jan/.config/systemd/user/kicad-build.timer; enabled; preset: enabled)
     Active: inactive (dead) since Sat 2023-03-04 09:54:42 CET; 11min ago
   Duration: 1month 2w 5d 13h 3min 15.725s
    Trigger: n/a
   Triggers: ● kicad-build.service

Jan 13 10:21:26 memory-alpha systemd[901]: Started KiCAD nightly build timer.
Mar 04 09:54:42 memory-alpha systemd[901]: Stopped KiCAD nightly build timer.

进一步测试：

[jan@memory-alpha user]$ gdbus introspect --system --dest org.freedesktop.systemd1 --object-path /org/freedesktop/systemd1 | grep DisableUnit
      DisableUnitFiles(in  as files,
      DisableUnitFilesWithFlags(in  as files,
      DisableUnitFilesWithFlagsAndInstallInfo(in  as files,

[jan@memory-alpha user]$ gdbus introspect --session --dest org.freedesktop.systemd1 --object-path /org/freedesktop/systemd1 | grep DisableUnit
      DisableUnitFiles(in  as files,
      DisableUnitFilesWithFlags(in  as files,

显然我的系统会话有适当的方法，尽管我的用户会话没有。不幸的是我对 D-Bus 的了解不够，无法进一步调试这个问题，有什么想法吗？

[jan@memory-alpha user]$ uname -a
Linux memory-alpha 6.1.4-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 07 Jan 2023 15:10:07 +0000 x86_64 GNU/Linux

[jan@memory-alpha user]$ systemctl --version

答案1

您的系统正在运行 systemd 版本，该版本与 systemctl 版本相比太旧。 （此 D-Bus 方法是在 systemd v253 中添加的。）

用于systemctl [--user] daemon-reexec升级正在运行的 systemd 版本。
